Abstract. xsmle is a new user-written command for spatial analysis. We consider the quasi–maximum likelihood estimation of a wide set of both fixed- and random-effects spatial models for balanced panel data. xsmle allows users to handle unbalanced panels using its full compatibility with the mi suite of commands, use spatial weight …ting panel-data models. When T>N, one may use for these purposes the Lagrange multiplier (LM) test, developed by Breusch and Pagan (1980), which is readily available in Stata through the command xttest2 (Baum 2001, 2003, 2004). On the other hand, when T<N,theLM test statistic enjoys no desirable statistical properties in that it 1.Researchers perform cointegration tests when time series are nonstationary to determine whether they have a stable, long-run relationship. xtcointtest implements a variety of tests for data containing many long panels, known as the large-N large-T case.

If you just specify panel and year variables, Stata expects unit spacing, so lag 1 with yearly data means "the previous year". Asking for a lag 1 variable is legal, but all values are missing. xtset ID Year gen lag1 = L1.Y. If you specify delta (5) then a lag 1 variable is missing in all but two observations. xtset ID Year, delta (5) gen lag5 ...Panel data are a type of longitudinal data, or data collected at different points in time.
